Abstract

This essay takes the position, consistent with Ayer’s own retrospective judgments, that the philosophical significance of Language, Truth and Logic (LTL) was minimal at best, and that its real significance was socio-historical. LTL stands as one of the most influential expressions of an overzealous and simplistic scientism that swept through Western culture in the first half of the twentieth century. This scientism played a crucial role in problematizing the West’s relationship to truth in ways that contributed to the eventual emergence of “post-truth” culture, with its “post-truth politics.” This in turn made possible the disastrous results of recent votes and elections in Britain and, above all, in the United States. In short, LTL’s real significance resides in the role it played as a sophisticated and successful bit of propaganda for an ideology that played a crucial role in loosing Western culture from its moral and epistemic moorings.
